# WARNING about open_files_limit and ulimit -n
|
||
|
|
#
|
||
|
|
# mysqld checks how many files can be opened on the machine,
|
||
|
|
# and this is by definition very:
|
||
|
|
# - os dependent, see OS_FILE_LIMIT, HAVE_GETRLIMIT
|
||
|
|
# - configuration dependent, for each machine (ulimit -n), see
|
||
|
|
# my_set_max_open_files() in mysys/my_file.c,
|
||
|
|
# see getrlimit(RLIMIT_NOFILE)
|
||
|
|
#
|
||
|
|
# Based on the this, the server tunes _down_ max_connections and
|
||
|
|
# table_cache_size to match the open_files_limit found,
|
||
|
|
# which significantly interfere with this test.
|
||
|
|
#
|
||
|
|
# Solution: use a big table definition cache,
|
||
|
|
# but small values for max_connection and table_open_cache,
|
||
|
|
# to stay within open_files_limit of 1024.
|
||
|
|
#
|
||
|
|
# This is the best test we can do that has a chance to pass on all
|
||
|
|
# platforms, while still providing code coverage.
